Also have you tested this only Windows* 8 or also Windows* 7? (if you tested Windows* 7 did you experience the same issues?)

Also let us know what BIOS version you have on the NUC? (In the Operating System press the windows key and R, type msinfo32 and hit enter) and the on the right side of the window is should list BIOS Version/Date

I'm having the same problem with my Intel Nuc (DC3217IYE, latest bios) and a Intel Centrino 6230 wifi card (latest intel drivers) on Windows 8 64bit. BT works fine but no wifi! The wireless adapter does not show up in the device manager.

I'm having the exact issue as the original post suggests. My box is an Intel NUC Kit DC53427HYE, and I have installed all available drivers prior the installation of WiFi card Centrino 6235. After the installation, I installed both the WiFi driver Wireless_16.7.0_e164.exe and the bluetooth driver BT_3.1.1311_e164.exe. Since then, the bluetooth has just worked perfectly fine, yet no Wireless Adapter was found in Device Manager from Windows 8.1 x64 (fully patched as of 3/2/2014), nor any unknown devices.

However, I'm having another issue, which I cannot boot into BIOS setup program (F2 doesn't work, though I'm not sure if it's related to the fact I have enabled Fast Boot and General Boot Optimization previously).

The BIOS revision is 0030, flashed by RKPPT10H.86A.0030.EB.WINPE64.EXE.

Torg, I want to thank you for the pictures and information you provided. I verified that it is possible to RMA an Intel® NUC component with your nearest Intel® support team.

Can you comment about your results after replacing the preinstalled adapter with the Intel® Centrino Advanced-N 6205? Remember that not all driver versions apply to all wireless adapters and operating systems.
